19-3154; Rev 1; 5/05 EVAALVUAAILTAIOBNLEKIT Low-Cost, Current-Mode PWM Buck Controller with Foldback Current Limit General Description The MAX1954A synchronous current-mode, pulsewidth modulation (PWM) buck controller is pin patible with the popular MAX1954 and is suitable for applications where cost and size are critical. The MAX1954A operates from an input voltage range of 3.0V to 13.2V, independent of the IC supply. The output voltage is adjustable down to 0.8V. The IC operates at a fixed 300kHz switching frequency and provides up to 25A of output current with efficiency up to 95%. This controller has excellent transient response resulting in smaller output capacitance. The...
